U once mentioned Mabel going into a dream state, an infinite summer she wouldn't want to leave. What if that's what's happening? But as she attempts to escape this dream it becomes a nightmare? Bill thinks her worst fears would be better to hold her down instead of a dream. The bubble can't contain all the fears she holds deep inside and is breaking. And the only reason she wanted to leave the dream in the first place was because she heard Dipper over the walks-talky. (Idk just a theory)
Mabel being aware and not being aware. Her dream is her developing nightmare haunting her every step and she has to escape she has to get out but she can’t and from the shadows comes a distorted voice.
Mabel, it keeps saying and it sounds like Dipper but he’s right in front of her?
But he’s right there and it doesn’t make any sense so she makes a test. Does he want to play girly games? Does he want to have makeovers? Well of course he does, Mabel! Don’t be silly.
And she knows he’s a fake so she tries to run but there’s Dipper. Don’t you want to play, Mabel? Don’t you want to play a game with me?
Don’t you want summer to last forever?
Mabel says no. No, she doesn’t want summer to last forever she wants her brother, she wants her family she doesn’t want this.
And the first crack appears.
